The Nami Burn-E 2 Max (often called the "Viper") is not a scooter for beginners—it is a high-performance machine designed to replace a car. With its customizable ride parameters, sine wave controllers, and best-in-class hydraulic suspension, it offers a ride quality that few competitors can match. While it is heavy and cumbersome to transport, for enthusiasts seeking raw power combined with a "cloud-like" ride, this remains the gold standard in the 72V category.

TL;DR Quick Look
- Exceptional Ride Quality: The adjustable hydraulic coil-over suspension provides one of the smoothest rides in the industry.
- Massive Range: Real-world tests confirm it can exceed 50 miles on a single charge.
- Customizable Power: The large display allows deep tuning of acceleration and braking for each motor individually.
- Heavyweight: Weighing over 100 lbs, it is not portable for stairs or public transit.
- Industrial Design: The tubular frame is welded by hand, giving it a unique, rugged aesthetic but raising questions about finish consistency.

Real-World Performance
📺 Video: Nami Burn E real world performance review
The Burn-E 2 Max is defined by its sine wave controllers, which deliver power with incredible smoothness unlike the jerky start of square wave systems.
Acceleration
RiderGuide's data indicates this scooter is among the quickest production models available. The launch is ferocious yet controlled. While we lack specific 0-30 mph split times in the input data, the consensus from multiple review outlets is that the torque is sufficient to spin the wheels if traction control isn't modulated.
Top Speed
FluidFreeride and other retailers rate the top speed at 60 mph. User reports verify this, with one owner stating they reached 56 mph (90.5 km/h) in "X mode". It holds stability well at high speeds, thanks to the steering damper usually included or recommended as an upgrade.
Hill Climb
The torque from the dual 1500W motors makes hills irrelevant. RiderGuide testing placed the Burn-E 2 Max as the "4th quickest production scooter" on their 10% grade test. It accelerates up steep inclines where lesser scooters would stall.
Range Test
Range anxiety is virtually non-existent on this machine, provided you understand the difference between "claimed" and "real-world" range.
- Official Claims: Manufacturers claim between 90 to 115 miles depending on the riding mode (typically Eco mode).
- Independent Media Tests: The Electric Scooter Guide (ESG) review team achieved a tested range of 53.3 miles (85.7 km). This is a high-performance test figure, meaning aggressive riding will still yield over 50 miles, which is outstanding.
- User Reports: One owner reported achieving 40 miles while maintaining a high average speed of 35.6 mph, ending the ride with battery to spare.
Data Missing: Specific ambient temperature during these tests was not provided.
Ride Quality & Ergonomics
This is where the Nami shines brightest.
Suspension
The proprietary adjustable hydraulic coil shocks allow you to dial in rebound and preload. Whether you are a 150 lb rider or a 250 lb rider, you can tune the bounce to eliminate road vibrations. It floats over potholes and speed bumps.

Cockpit & Display
The large, central display is a standout feature. It provides clear visibility of speed, temperature, and battery voltage. More importantly, it allows granular control over the controller settings—you can adjust the front and rear motor power output independently (e.g., 80% front, 100% rear) to suit your riding style.

Portability
The folding mechanism uses a tapered thread system which is extremely rigid but slow to operate. Once folded, the scooter is still massive. At 103 lbs, lifting it into a car trunk is a two-person job for many.
Safety & Braking
Braking Performance
Stopping power is handled by Logan 4-piston fully hydraulic brakes with 160mm rotors. RiderGuide tests recorded a stopping distance from 15 mph of just 9.7 feet. This is top-tier performance, crucial for a scooter capable of 60 mph speeds.

Lighting
The scooter features a remarkably bright 2000-lumen headlight, making night riding safer than most stock scooters. Integrated turn signals are present, though low-mounted, which can sometimes be missed by car drivers.
Wet Performance
The scooter generally carries an IP55 or IPX5 rating. While the controllers are potted and connectors are waterproof types, Reddit users debate the "garden hose" test. Some advise caution against heavy rain, noting that "water resistant" does not mean "waterproof."
Data Missing: Specific wet surface braking distances are not available.
Reliability & Support
Common Issues
Early generations of the Burn-E (Viper) suffered from stem wobble issues due to the folding latch design. The "Burn-E 2" and "Max" versions have largely addressed this with a redesigned steel shaft system. However, users should still check the steering limiters and ensure the folding clamp is properly tightened before every ride.
Support
Buying from a reputable dealer is critical. In the US, FluidFreeride provides warranty support. Parts availability is generally good, but as a high-performance boutique brand, it requires more maintenance attention than a budget commuter.
Competitor Comparison
The Nami Burn-E 2 Max sits in the "Hyper-Scooter" category. Here is how it compares to its main rival.
| Model | Price | Claimed Range | Tested Range (ESG) | Top Speed | Weight | Core Pro | Core Con |
|---|---|---|---|---|---|---|---|
| Nami Burn-E 2 Max | ~$4,000 | 115 mi | 53.3 mi | 60 mph | 103 lbs | Best Suspension | Heavy/Industrial look |
| Wolf King GTR | ~$4,000 | 112 mi | ~55 mi (Est) | 65 mph | 134 lbs | Removable Battery | Massive/Heavy |
| Vsett 11+ Super | ~$3,500 | 100 mi | ~45 mi (Est) | 50 mph | 128 lbs | Stability | Dated Display |
Note: Competitor data is based on general market knowledge for comparison context.
Who Should Buy
- Heavyweight Riders: The suspension and power train handle heavier loads (220lbs+) without sagging or slowing down.
- Long Distance Commuters: If you need to cover 40+ miles at speed reliability.
- Tech Geeks: Riders who want to customize throttle curves and motor balance via the display.
Who Should Not Buy
- Apartment Dwellers: Carrying this up even a single flight of stairs is a nightmare.
- First-Time Owners: The power is overwhelming and potentially dangerous for inexperienced riders.
- Public Transit Users: It will not fit comfortably on a bus or train.

FAQ
Is the stem wobble issue fixed?
Yes, the "Burn-E 2" series features an updated folding mechanism and stem design that resolved the early wobble issues found in the original Viper models.
Can I ride it in the rain?
The scooter has an IP55 rating and waterproof connectors. It can handle light rain and wet roads, but submerging it or riding in torrential downpours is not recommended by the community or manufacturer.
What is the difference between the standard Burn-E 2 and the Max?
The "Max" version typically features a larger battery (40Ah or 32Ah LG cells vs. generic 28Ah) and higher peak power output from the motors, resulting in better range and acceleration.
How long does it take to charge?
With the stock chargers (often two are provided), charging the massive 72V battery takes approximately 6-8 hours.
